Engraving A Puzzle Box? Here’s A Collection Of Single-Line Cryptex Fonts

Here’s a neat resource from [MSRaynsford] that is worth bookmarking for anyone who gets creative with laser engravers, CNC routers, or drawing robots: SVGFonts are single-line symbol fonts that [MSRaynsford] created for his laser-cut and engraved cryptex puzzle boxes. They provide an easy way to engrave text as symbols.

Single-line fonts for engraving that include a runic-looking alphabet, a Greek-inspired set, and two symbol sets based on Flag Semaphore.

CNC engraving of letters and symbols is one of those things that seems simple, but is actually more complex than it may appear. It is often desirable to use a tool to engrave symbols with a single line, in much the same way a person would write them if using a pen. But fonts and art for letters and numbers aren’t normally a single line. Thankfully there is a solution in the form of Hershey text, an extension for which is included in Inkscape. It turns out that Hershey Fonts have their origin back in the 1960s, when the changing landscape of electronics and industry opened new opportunities and demanded new solutions.

That’s why, when [MSRaynsford] needed fonts in different styles and symbols for creating his puzzle boxes, he had to design them himself and they had to be single-line vector art, just like Hershey Text. The small collection includes English letters designed to resemble a runic alphabet, a Greek-inspired series, and two coded alphabets based on flag semaphore.

Grab ’em on GitHub, because you never know when you’ll need to make a quick cryptex.

Perlin Noise Helps Make Trippy Typographic Art

Perlin noise is best explained in visual terms: if a 2D slice of truly random noise looks like even and harsh static, then a random 2D slice of Perlin noise will have a natural-looking blotchy structure, with smooth gradients. [Jacob Stanton] used Perlin noise as the starting point for creating some interesting generative vector art that shows off all kinds of different visuals. [Jacob] found that his results often exhibited a natural quality, with the visuals evoking a sense of things like moss, scales, hills, fur, and “other things too strange to describe.”

The art project [Jacob] created from it all is a series of posters showcasing some of the more striking examples, each of which displays an “A” modified in a different way. A few are shown here, and a collection of other results is also available.

Perlin noise was created by Ken Perlin while working on the original Tron movie in the early 80s, and came from a frustration with the look of computer generated imagery of the time. His work had a tremendous and lasting impact, and was instrumental to artists creating more natural-looking textures. Processing has a Perlin noise function, which was in fact [Jacob]’s starting point for this whole project.

Noise, after all, is a wide and varied term. From making generative art to a cone of silence for smart speakers, it has many practical and artistic applications.
